Last I checked, Combo boxes play nicer with char surogate keys than integers.

Not that you asked for this, but for the record, here are some times that show how much faster ints are: http://fox.wikis.com/wc.dll?wiki~IntVsChrSpeed~VFP

>The only good reason I can think of to use a character based primary key is that it allows for the use of concatinated keys. This ability doesn't seem to out-weight the performance issues so why would I ever use a character based primary key? Am I missing the boat here? Is there some hidden advantage to it? If not, why do most all of the frameworks I have looked at default to it?
